Bridge Constructor

There is a pretty cheap way to pass some of these levels with minimal resources. You can simply running a steel cable underneath the wooden bridge and connect a few nodes with vertical pieces of wood. It will not be stable at all or look pretty, but at least you'll pass the level! I have taken screenshots of each of my set-ups and included them below for your help. These set-ups also work for the trucks. To save time, only run the trucks over these bridges to unlock this stackable achievement.
